Specification of Letters Patent.

l'atontcd d'une 12; 19065 Application filed January 1 2, 1906. Serial No. 295,722.

To allwhom it may concern:

Be it known that I, JAMES P. SNELGROVE, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have made certain new and useful Improvements in Door-Fasteners, of which the following is a specification.

My invention is an improvement. in doorfasteners; and it consists in certain novel constructions and combinations of'parts hereinafter described and claimed.

Referring to the drawings forming part hereof, Figure 1 is a perspective view of the complete fastener. Fig. 2 is a detail view of the plate. Figs. 3 and 4 are detail views of the handle from the front and side. Figs. 5 and 6 are detail views of the latch, Fig. 6 being a longitudinal section and Fig. 5 a front view with part of the enlarged portion broken away; and Fig. 7 is a transverse section through a sliding door provided with my improved fastener.

In the practical application of my invention,I provide a plate A, having at one end thereof a journal-pin a provided with a head 0;, the plate being provided with a plurality of holes a (1, whereby it may be secured to a c oor.

A latch B is pivoted u on the j ournal-pin, the latch comprising a pl ate provided at one end with a lug b and at the other end with an enlarged portion 1), bifurcated, as at 6 to form a notch. The edges of the notch are recessed, as at 5 to form a circular opening for receiving the journalpin, that art of the notched portion below the journa pin being recessed to form bearings b.

A handle 0 is provided at its upper end with trunnions c for engaging the bearings and near its lower end with a perforation c for a purpose to be hereinafter described. The handle O swings upon an axis at right angles to the axis of the journal-pin, and when it is swung upward and outward through an arc of ninety degrees it will be in the same horizontal plane with the plate A. It will be evident that when the handle is in the above position a swing to the left will bring it into contact with the plate.

A yoke D, provided with a screw-threaded body portion d, traverses the opening a in the plate, the arms d of the yoke projecting outwardly therefrom. The screw-threaded body portion engages the door or other part to which the plate is attached, thus assisting in securing the plate, an ordinary bolt traversing the opening a. The arms of'the yoke are provided with alined perforations d and are adapted toengage thearm-C when. it. is swung inwardly into contact with-the plate, the perforations d registeringwith the perforation c in the handle.

A. keeper E, provided with openings 6, whereby it may be attached to the side ofthe car or building of which the door. isapart, .is provided with an inverted L-shape opening a for receiving the lug and latch and with a rearwardly-projecting lug e for engaging the lug of the latch. In assembling my improved fastener the trunnions of the handle C are engaged in the bearings 12, after which the plate is passed through the notch until the journal-pin engages the circular opening. The plate and the keeper may then be secured in place.

In operation, the door being closed, the handle 0 is swung upwardly and outwardly through an arc of ninety degrees, the lug and latch passing through the upper portion of the L-shape opening until the lug on the latch is engaged behind the lug of the keeper. The handle C at this time is in the horizontal plane of the plate A, and when the handle is swung to the left it will be engaged by the arms of the yoke B. A seal may, if desired, be passed through the alined openings in the arms of the yoke and in the handle, thus securing all the parts in their locked position.

My improved fastener is especially adapted for car-doors, although it is evident that it may be used upon any class of sliding doors. When so used, it obviates the necessity of cleating the door and when sealed cannot be unlocked without breakin the seal. It is easily assembled, and bro en parts can be easily replaced. With my improved fastener there is but little liability of breakage from swinging outward of the door, since in such swinging the stress will be directed outward, which stress the latch is especially designed to resist.

What I claim is 1. A fastener for doors comprising a keeper, and a plate having at one end a headed ournal-pin, a yoke on the plate having projecting arms provided with alined perforations, a latch having at its upper end a lug for engaging the keeper, and at its lower end a notch for receiving the plate, the sides of the notch being provided with recesses for receiving the journal-pin, the latch having bearings below the recesses and at right anthe arms.

2. A fastener for doors comprising a plate, a latch mounted to rotate transversely of the plate, a handle for manipulating the latch, said handle being pivoted to the latch for movement at a right an le to the plane of movement of the latch, a keeper for engaging the latch and a yoke on the plate having arms for receiving the handle.

3. A fastener for doors comprising a keeper, a plate having a swinging latch, an arm whereby to swing said latch transversely of the plate to engage the keeper, means whereby said arm may swing at a right angle to the plane of movement of the latch, said plate being provided with means for engaging the arm whereby to lock the latch in engagement with the keeper.

4. A door-fastener comprising a keeper and a plate having a swinging latch, means for swinging the latch into engagement with the keeper, comprising an arm pivotally mounted on the latch for movement in a plane at right angles to the plane of the movement of the latch, and means for engaging and retaining the arm at the end of said movement.
